Title: Method for broadcasting a digitally coded stream of data
Inventor: PLENGE GEORG
IPC: H04H20/33
Filed: 1992-04-08
Granted: 1998-06-16
Abstract: In order to permit an already occupied frequency spectrum to be utilized for the radio transmission of a data stream without interfering with the services already established there, a plurality of the RF carriers modulated with the data stream are either transmitted in the frequency gap between two adjacent frequency FM services at the same location or in the free frequency ranges at both sides of an FM service, while leaving out its rated frequency occupation.  Compared to the level of the RF carrier of the adjacent frequency FM service or the FM service in the middle, the level of the plurality of RF carriers is selected to be sufficiently low in the sense of a signal to noise ratio that is sufficient for FM reception of the FM service or services.  Moreover, the mentioned level is selected to be sufficiently high in the sense of noise immunity against more remote FM services which fall into the frequency range or frequency gap intended for the transmission of the plurality of RF carriers.  The data stream modulating the RF carriers is provided with increased error protection in the sense of providing sufficient noise  immunity against the adjacent frequency FM service or services or the FM service or services in the middle.

Granted: 1997-04-08
Abstract: Shrimp and other food products carried on a plastic modular conveyor belt are efficiently cooked at atmospheric pressure in the presence of saturated steam protected by a confining receptacle from dilution by insulating air. The steam condenses by transfer of cooking energy, the condensate dropping downwardly in the receptacle by gravity. By passing products through the constant 212 degree F saturated steam zone residing at the upper portion of the cooking receptacle, the belt speed and distance through a modular cooking compartment control the cooking time for uniform production. The steam is replenished through a proportional flow valve to replace only that amount of steam expended in cooking. Thus, temperature is sensed at a cooler position under the saturated steam cooking zone where temperature is typically 190-200 degrees to detect variations of the amount of steam condensed in exchange of heat in cooking the product, and to proportionately control the flow of replacement saturated steam. Critical control of cooking receptacle rejection or contaminating air maintains a substantially static pure saturated steam layer in the upper portion.  The lower portion contains lower temperature air/vapor mixture. The access doors are sealed by an expandable gasket tube. This permits simplified fully automatic steam replenishment and efficient cooking without losses of energy from either excessive steam flow, dilution of saturated steam cooking efficiency from air or fluid vapors admitted into the cooking receptacle or losses at the doors.

Abstract: A method and apparatus for ventilating pocket spaces in a multi-cylinder dryer of a paper machine, in particular a high-speed paper machine whose running speed is higher than about 800 meters per minute, in the area of a so-called twin-wire draw.   In the twin-wire draw,  the drying cylinders in the drying group are arranged in two rows placed one above the other, in which rows the successive cylinders are placed in the upper row and in the lower row as interlocked.  In each cylinder group, there are two drying wires, an upper wire and a lower wire for pressing the paper web against heated faces of the drying cylinder while being guided by guide rolls placed in gaps between the cylinders.  The paper web runs as free draws between the rows of cylinders.  Pocket spaces are formed in the area between the free draws of the web and the upper wire and its guide roll and the drying cylinder in the lower row and, in a corresponding manner, adjacent pocket spaces are formed in the area between the free draws of the web, the lower wire, its guide roll, and the drying cylinder in the upper row. The pocket spaces are ventilated by pumping air induced by the wire in the multi-cylinder dryer, wherein, at the inlet side of the guide roll, the wire pumps air into the pocket spaces through the wire and wherein the wire pumps air out of the pocket spaces at the outlet side of the guide roll of the wire.  Air being pumped out through the wire on its run at the outlet side from the guide roll to the following cylinder is limited as compared with free pumping-in and pumping-out so as to control the pressure level and/or the flow status in the pocket spaces.

Abstract: Method and apparatus for bending serpentine heat exchanger tubes using a split bend die having a relatively short upper die section with a straight back end. After the tube is bent in conventional manner using a clamp die and a pressure die, the bend die is split along a shaft and rotated through a predetermined angle to position the straight back end substantially parallel to a straight segment of the tube at the output of the bend die. The input segment of the tube is then moved next to the shaft in preparation for rotating about the input segment to raise the output segment above the upper section of the bend die.    Such lateral motion reduces the segment spacing required for clearance of the upper section. Other features for reducing the spacing are providing an indentation on the shaft, angling the back end with respect to the sides to provide a minimum length, and truncation an upper portion along the back end.

Granted: 1999-11-16
Abstract: In a mobile radio communication system for performing radio communication between a base station and a plurality of mobile stations by a code division multiple access method, a plurality of slots (T1 to T4) for a forward link from a base station (BS) to a mobile station (MS) and a plurality of slots R1 to R4 for a reverse link from the mobile station (MS) to the base station (BS) are set on a first radio frequency f2 in a time-division multiplexing manner.  The slots are set in accordance with the distance between the base station and the mobile station, and the transmission power of the base station in each slot is associated with this distance.  The transmission power is low in the slot associated with a short distance between the base station and the mobile station, and the transmis-sion power is high in the slot associated a long distance between the base station and the mobile station.  The mobile station (MS) detects the received electric field intensity of a pilot/sync signal coming from the base station (BS) with a second radio frequency, and sends the detected information to the base station (BS).  On the basis of the detected value of the received electric field intensity of the mobile station (MS) sent from the mobile station (MS), the base station (BS) determines the distance between the base station and the mobile station, selects the associated pair of slots from among the pairs of slots T1/R1 to T4/R4, thereby allocating the selected slots to this mobile station (MS).
